[Pgday.Seoul 2018] 이기종 DB에서 PostgreSQL로의 Migration을 위한 DB2PG

  1. 1. DB2PG
  2. 2. - 비용절감? - 정책 이슈 - 성능, 기능이슈 - 사용상의 편의성 - Cloud등으로의 환경변화 - 기타 등등 . . .
  3. 3. - Oracle이외의 DB는 어떤 tool로? - ora2pg의 성능(대용량) - Perl engineer? NO, java engineer? Yes - 수작업 ㅠㅠ - 국가정보자원관리원 Project진행
  4. 4. - 2016. 05월 사내 Project로 시작 - 2017. 03월 Oracle Spatial data 지원 - 2017. 10월 MS-SQL 지원 - 2018. 05월 공개SW 기술개발 지원사업 참여 - 2018. 06월 OpenSource화 결정 및 Github - 2018. 10월 Oracle, DB2, MS-SQL, Sybase, Mysql지원
  5. 5. - 제품별 데이터 구조의 호환성 - GIS데이터와 같은 특수한 데이터 변환 - DB별 개성적인 DDL - Resource 부족(개발자, DBA)
  6. 6. - PostgreSQL 시장확대 - 공개SW 기술개발 지원사업 참여 - 개발자의 참여 유도(능력자필요) - K4M value up!
  7. 7. DBMS DDL Extract Data Migration Oracle Yes Yes MS-SQL Yes Yes DB2 Yes Sybase Yes Mysql Yes Yes cubrid, altibase Soon
  8. 8. - Schema - Tables - Primary key - Unique - Foreign Key - View - Sequence - Index
  9. 9. Github db2pg / / Images / / setting / convert_map.json / setting / mapper / MetaExtractMapper.xml / src/main/java : java source
